NON-REFILLABLE BOTTLE.

SPECIFICATION forming part of Letters Patent No. 657,863, datedSeptember 11, 1900.

Application filed beptember 27, 1899, Serial No. 731,849. lNo model.)

To all witmn it may concern:

Be it known that I, SAMUEL DAVIS, a citizen of the United States,residing at New York, borough of Manhattan, county and State of NewYork, have invented new and useful Improvements in Non-RefillableBottles, of which the following is a specification.

This invention resides in certain novel features of construction setforth in the following specification and claims and illustratedin theannexed drawings, in which Figure 1 is a sectional view of a bottleupright and corked. Fig. 2 shows a bottle uncorked and tilted or upsetfor pouring out. Fig. 3 is a section along 00 m, Fig. 1. Fig. 4 is asection along y y, Fig. 1. Fig. 5 is a sectional view of a modification.Fig. 6 isan inverted plan view of Fig. 5.

The neck of a bottle is shown at a, said neck having its lower partcontracted or constricted, as seen at ct. A valve-seat is shown with avertical or mouth portion 1) and inclined portion 1). A valve or cap isof corresponding shape to fit both valve portions, this valve having thevertical portion 0 and inclined portion 0. This valve or cap is outsideof the seat, and when the bottle is'upright, Fig. 1, this valve willdrop onto its seat to form a closure. The valve has a stem d, guided bythe seat I). The seat is shown with a bar or cross-piece 6, throughwhich the stem d is passed or guided. This bar is a magnet and forms aholder for drawing or holding the valve to its seat. As long as liquidis in the bottle the weight of such liquid on the tilting of the bottlecarries the valve from its seat, so that the bottle can be emptied.When, however, the bottle is empty and is reversed, the valve being heldor attracted to its seat seals or closes the bottle against refilling.The valve when on its seat acts as a keeper for the magnet e.

The valve-seat is shown with a cylindrical part b and flange 6 A packingor cork f between the valve-seat and the bottle-neck secures a tightjoint and holds the seat in place in the neck. The seat having beenprovided with the packing f can be pushed or jammed into the neck asuitable distance, the contraction a preventing the seat being forcedinto the bottle.

In Fig. 5 the seat is shown without parts b and b but is provided withteeth b adapted to pierce or engage the packing f, so that the packingand valve-seat together can be forced or pushed into place in thebottle-neck. In Fig. 1 the flange 1) forms a seat or holding device forsupporting the packing f.

A guard or sleeve g protects the valve against tampering, as by theinsertion of a wire or instrument intended to catch under incline c tolift or move the valve from its seat. This guard is shown with a numberof projections g. Four such projections have been found satisfactory,but of course this number can be changed. The neck a has seats ordepressions corresponding to projections 9', and the projectionscatching into the seats hold or secure the guard in place. A grooveabout the neck is not as satisfactory as individual seats at g if avalve-seat with flange b is employed, since such a groove is apt tocatch or interfere with the insertion of the valve-seat or its flange 5The guard or its projections g are made of sufficiently springy ornon-rigid material to be crowded down the neck a, and then to expand orsnap into the depressions to catch hold. WVhen the cork h is in place,Fig. 1, a rod or wire t'between the cork and valve 0 can lock or holdthe latter to its seat, so that in shipping or storing the valve cannotdrop or be jarred from its seat. No part of the bottle contents can thussettle between the valve and the cork.

What I claim as new, and desire to secure by Letters Patent, is

1. A valve-seat having an upper vertical mouth portion, an incline b anda cross-bar fixed in the upper or mouth portion, the lower or enlargedportion of the seat being left unobstructed or without any cross-piece,a valve of corresponding shape to fit both portions of the valve-seat, aguiding-stem sliding in the cross-bar and depending from the under partof the valve and secured to the latter so as not to project above thesame, and a guard g above the valve, the space between the valvetop andguard being left empty or unobstructed to leave the valve free to moveback and forth, substantially as described.

2. A valve-seat having an upper vertical mouth portion, an incline b anda cross-bar fixed in the upper or mouth portion, the lower cross-bar anddepending from the under part of the valve and secured to the'latter soas not to project above the same, and a. guard g above the valve, thespace between the valvetop and guard being left empty or unobr0 structedto leave the valve free to move back and forth, said'cross-bar beingmagnetic to hold or attract the valve to its seat, substan tially asdescribed.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing I5 witnesses.
